El plomo es un elemento químico de la tabla periódica, cuyo símbolo es Pb (del latín plumbum) y su número atómico es 82 según la tabla actual, ya que no formaba parte en la tabla periódica de Mendeléyev. Este químico no lo reconocía como un elemento metálico común por su gran elasticidad molecular. Cabe destacar que la elasticidad de este elemento depende de la temperatura ambiente, la cual extiende sus átomos. El plomo es un metal pesado de densidad relativa o gravedad específica 11,4 a 16 °C, de color plomo (gris oscuro), que se empaña para adquirir un color gris mate. Es flexible, inelástico y se funde con facilidad. Su fusión se produce a 327,4 °C e hierve a 1725 °C. Las valencias químicas normales son 2 y 4. Es relativamente resistente al ataque del ácido sulfúrico y del ácido clorhídrico, aunque se disuelve con lentitud en ácido nítrico y ante la presencia de bases nitrogenadas. El plomo es anfótero, ya que forma sales de plomo de los ácidos, así como sales metálicas del ácido plúmbico. Tiene la capacidad de formar muchas sales, óxidos y compuestos organometálicos.
